To all vwhom it may concern:

Be it known that I, HENRY E.-FLEDDER- JOHANN, a. citizen of the United States, re-

' siding at New Knoxville, in the county of.

Auglaize and State of Ohio, have invented a new and useful Twin cylinder Reversible- Spi-ral Turbine-Engine; and I do hereby declare the following to be a full, clear, and exact description of the -invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to new and useful twin cylinder reversible spiral turbine enne. As an object of the invention it is the aim to provide two cylinders, connected by a hollow spindle shaft, which not only acts as sage-ways, in which, at their inlet portion,-

a shaft, but constitutes means to convey the steam to the cylinder.

Another object of the invention is to provide each cylinder with spiral steam pastransversely disposed steam abutment'plates are arranged. To drive the cylinders in one direction, the steam from the hollow spindle shaft, is let into the steam passage-ways at one end of each cylinder, andto reverse the engine' or the motion of said cylinders, the steam is let into the passage-ways, at the other end of each cylinder.

Another object of the invention is the fact that this type of engine can be so constructed, as to be placed in the lower part of a boat, out of the way. because it requires '5 but little room or space, and not such a very strong or massive foundation, especially because there is scarcely any jar, provided the engine is well balanced.

Another object of the invention is the factthat this engine may be reversed at a molnents warning, whether at sea or upon rivers. Furthermore, the engine may be used upon locomotives with exceedingly great efficiency.

Another feature of the invention, is the eliminating of the side thrust, found in other types of engines, owing to the provision of the hollow spindle or shaft connecting between the cylinders.

There are disclosed in the drawings certain features of construction, but in practical fields these features may necessitate alterations, to which the patentee is entitled, provided the alterations fall within the scope of what is claimed.

The invention comprises further features thereof, and also showing clearly how the steam can be carried to one end of each cylinder to enter the passage-ways, to rotate the cylinders in one direction, and further showing how the steam can be controlled, to enter the other end ofeach cylinder and the passage-ways thereof to rotate the engine in the opposite direction. Fig. 5 is a transverse sectional view on line 5-5 of Fig. 4. Fig. 6 is an enlarged detail sectional view of a portion of one of the cylinders.

Referring more particularly to the draw ings, 1, 2 and 3 designate steam chests, of any conventional or suitable construction, and into which steam is conveyed by way of the pipes or conduits 4, 5 and 6, which unite chest 1 has a hollow spindle shaft extending from each end, one designated by the numeral 9 while the other is denoted by the numeral 10. The spindle shafts are mounted in bearings 11', and are extended into the members or bearings 12 and-13 of the cylinders 14 and 15. Extending from the steam chests 2 and 3 are hollow spindles 16 and 17, which fit the members or bearings 18 and 19 of the cylinders 14 and 15. The members or bearings 12 and 13, and 18 and 19 consist of short sleeves, the ends of which are threaded or otherwise secured inthe plates 20 and 21, and 22 and 23 of the cylinders. These members or bearings 12 and 13, and 18 and 19 are provided with perforations in their circumferential walls, through which perforations the steam passes from the spindles 9 and 10, and 16 and 17, and into the spaces 24 and 25, between the plates 20 and 21 and 22 and 23. The perforations of the members or bearings 12 and 13, and

and combination of parts, as hereinafter set nesses of the walls of said shells are suiticient, in order that the passages or grooves may be constructed with suflicient depth, 1n order to receive a large body or quantity of steam. The passages 28 and 29 at each end of each cylinder merge from the annular passage-ways 30 and 31, nto which the steam enters by way of the perforations 32 and 33, from the spaces 24111151 25.- The plates 20 and ,22 are arranged in the ends of said cylinders, against the shoulders 34: and 35, while the plates 21 and 23 are arranged against the shoulders 36 and 37, being held in such positions, by vlrtuewofthe members 38 in the recesses 39 of the said shells of the cylinders. This method of'con- 'struction insures a light, yet strong and ex.,

tremely durable revoluble cylindrical body, which will not only revolve with great speed, but will rotate even or with uniformity. Y

Located at the inlet end of each passage 28 and 29.is a series of transversely disposed steam abutment blades or members 40 and 41, against which the steam acts as it enters each passage-way 28 and 29, in order to impart revoluble motion to each cylinder. The first blade a. of each series is provided with a single aperture, while the next blade is pro vided with two apertures, whereas the third blade is supplied with four apertures. The number of these blades in each series may be increased or decreased, as the case may require. It is obvious why only one aperture is provided in each of the first blades a. F or instance, the provision of only "one aperture only allows a certain amount of steamor other fluid to pass through the first blade. a into the space or pocket between the first blade and the second blade, thereby insuring a greater body of steambehind the first blade at, the expansion of which will impartmotion to the cylinder, while the in- I creased number of aperturesin thesecond and 'third blade allows a greater quantity of steam to escape from the said pockets 42 and 4.3. The steam passing through the third blade freely passes through the remaining portion of each spiral passage idly and exhausts at the outlet 44 of each passage. Shrunk or otherwise securely fitted upon the shells of said cylinders are cylin'- drical jackets 45 and 46 spaced apart at 47 in order to cover the spiral passages.

When the cylinders are rotating in the direction indicated by the arrows a ,'steam is being let into the passages at the adjacent ends of thecylinders, but to impart motion to the cylinders in the direction indicated by the arrow a steam is allowed to enter the passages 29 at the outer ends of the cylinders.

' The pipes 5 valves 47, while a valve 48.

and 6 are provided with the pipe 4 is provided with- To cause the steam to'enter the passageways 28 at the adjacent ends of the cylinders, the valves 47* are closed, while the valve 48 is open. To admit steam to the passages 29 at the outer ends of said cylinders, the valve 48 is closed while the valves 47 are open.

From the foregoing, it will be ascertained that there has been devised a simple and inexpensive yet extremely durable twln or multiple cylinder reversible spiral steam turbine engine, and one which has been found desirable and practical, owing to its exceptional adaptability upon sea-going ves- It wil l be observed that the entire engine is inclos'ed in an airtight casin 3 having haust steampasses The steam onentering the vacuum chamber is immediately condensed. This act-ion makes the vacuum chamber about 13 pounds less than air pressure. By the constant use of a vacuum pump (not shown), adapted to be connected to the vacuum chamber by means of an exhaust pipe 3*, shown in Fig. 2, the power of this engine may be greatly increased.
